<member name="buffer_length" type="float" setter="set_buffer_length" getter="get_buffer_length" default="2.0">
|
|
The length of the buffer to keep (in seconds). Higher values keep data around for longer, but require more memory.

<member name="fft_size" type="int" setter="set_fft_size" getter="get_fft_size" enum="AudioEffectSpectrumAnalyzer.FFT_Size" default="2">
|
|
The size of the [url=https://en.wikipedia.org/wiki/Fast_Fourier_transform]Fast Fourier transform[/url] buffer. Higher values smooth out the spectrum analysis over time, but have greater latency. The effects of this higher latency are especially noticeable with sudden amplitude changes.

<constants>
|
|
<constant name="FFT_SIZE_256" value="0" enum="FFT_Size">
|
|
Use a buffer of 256 samples for the Fast Fourier transform. Lowest latency, but least stable over time.
|
|
</constant>
|
|
<constant name="FFT_SIZE_512" value="1" enum="FFT_Size">
|
|
Use a buffer of 512 samples for the Fast Fourier transform. Low latency, but less stable over time.
|
|
</constant>
|
|
<constant name="FFT_SIZE_1024" value="2" enum="FFT_Size">
|
|
Use a buffer of 1024 samples for the Fast Fourier transform. This is a compromise between latency and stability over time.
|
|
</constant>
|
|
<constant name="FFT_SIZE_2048" value="3" enum="FFT_Size">
|
|
Use a buffer of 2048 samples for the Fast Fourier transform. High latency, but stable over time.
|
|
</constant>
|
|
<constant name="FFT_SIZE_4096" value="4" enum="FFT_Size">
|
|
Use a buffer of 4096 samples for the Fast Fourier transform. Highest latency, but most stable over time.
|
|
</constant>
|
|
<constant name="FFT_SIZE_MAX" value="5" enum="FFT_Size">
|
|
Represents the size of the [enum FFT_Size] enum.
